- E#m3G#M3B#m3D#
E# Minor 7, written E#m7, is built from E#, G#, B# and D#: the root, minor 3rd, 5th and minor 7th.
Its 3rd and 7th, G# and D#, are its guide tones: they say what kind of chord it is, so voicings are built around them and the root is often left to the bass.
In the progressions here, E#m7 is the vii7 of the Bebop Rhythm Changes in F#.
